DETAILED DESCRIPTION OF THE INVENTION

Traditional street parking meters are in the process of being phased out and replaced by meters that are enabled to accept modern methods of payments, e.g., credit cards, debit cards, smart cards, pay-by-phone, etc. Replacement and installation of an entirely new unit is costly for cities, municipalities, or other authorities in charge of street parking meters, thereby causing eventual increase in parking rates to recover the cost of purchase and installation. Moreover, replacement and installation of an entirely new unit creates electronic waste. The device described in the present invention, offers a cost effective and environmentally-friendly solution to the problem. The housing of the device of the present invention can be easily fitted to mount to the poles supporting existing street parking meters, even those parking meters that have previously been upgraded by replacing the internal meter mechanism. In contrast, installations of sensors in existing street meters typically involve excessive road work, drilling, and infrastructure modifications on street lights, utility poles, and underground wiring. The addition of the device described herein to existing parking meters by mounting the housing of the device to the poles of existing parking meters reduces waste, is easier to install, and is less expensive to maintain.

In certain embodiments, the device of the present invention is completely solar powered. Street parking meters that are upgraded using a solar powered device described herein do not need batteries to operate. This feature reduces the potential hike in operating cost of the street parking meters that are upgraded with the device described herein. In other embodiments, the sensor within the interior of the housing of the device is completely battery powered, completely wire powered, and/or optionally solar powered.

In certain embodiments, the housing of the device of the present invention defines an interior. The interior of the housing is equipped with one or more sensors configured to collect environmental information pertaining to the local external environment of the existing parking meter, and a wireless radio transmitter configured to transmit the collected environmental information either to the existing parking meter or to a remote server in communication with the existing parking meter. In certain embodiments, a sensor detects vehicles within the local environment of the parking meter on which the housing is mounted. In certain embodiments, a wireless radio transmitter communicates, directly or indirectly, with a remote management or maintenance server. In certain embodiments, the interior of the housing is also equipped with an RF tag reader. The RF tag reader can be used to read a wireless RF tag located on the base of an existing parking meter, and acquire information regarding the local environment. Information about the local environment can then be communicated, via a wireless radio transmitter, also housed within the housing, to a remote management or maintenance server. This allows immediate communication between the upgraded parking meter and the remote maintenance or management server. In this way, the housing of the device containing the sensor, RF tag reader, and wireless radio transmitter can communicate with a remote management or maintenance server and configure itself directly, independent of the device.

This results in reduction of energy costs associated with operating the meter. In certain embodiments, the meters rapidly switch on upon detection of vehicle presence by the sensors, and are ready for carrying out payment transactions even before the vehicle driver walks up to the meter.

In some embodiments, the sensor affixed to the housing of the device of the parking meter, communicates the information regarding the departure of the vehicle to the meter device or the existing meter and this results in immediate resetting of paid time. In further embodiments, the sensor affixed to the housing of the device of the parking meter, communicates through wireless radio, which in turn transmits the information to the wireless tag affixed to the parking meter, and this results in the update of the display screen of the parking meter and/or the device. Thus, the parking meters describe herein is optionally used to avoid overlap of paid time between successive vehicles occupying the same parking space. This enables collection of increased and accurate revenue from the parking meters of the present invention.

In certain embodiments, the vehicle presence information, within the parking space(s) associated with the parking meter, can be collected by the sensor and transmitted, via the wireless radio transmitter (along with location identification information stored in an RF tag associated with the parking meter), to one or more remote servers, a cluster of servers, or cloud computing system. The types of information transmitted to the server can include, for example, average length of time during which the parking space(s) is/are occupied and paid for, average length of time during which the parking space(s) is/are unoccupied and not paid for, days of the week with maximum occupancy and/or vehicle presence in the parking space(s), or times of the day with maximum occupancy and/or vehicle presence in the parking space(s). The information stored at the server is optionally utilized to model the vehicle flux trends within the local environment of the parking meter, and fix parking rates and/or time limits for parking to precisely meet the needs of the local environment.

EXAMPLES

The following illustrative examples are representative of embodiments of the software applications, systems, and methods described herein and are not meant to be limiting in any way.

Example 1—Installing the Device

A city maintenance technician performs his duties, which include driving around town and upgrading parking meters. He loads his vehicle with devices and a toolbox. When he approaches an outdated meter, he does not need to perform any major upgrades to infrastructure, such as drilling, underground wiring, road work, and the like. As such, he does not need any advanced or heavy tools, such as an industrial hammer drill. Instead, the technician uses his simple tools, for instance a screwdriver and a wrench, to attach the device to the pole of an existing parking meter. The entire process for replacing the housing of the device may require less than 10 minutes for completion. The technician then moves to the next parking meter.

Example 2—Installing Only a Portion of the Device

Technician from Example 1 is performing the same duties, except this time he is only replacing a portion of the device already installed onto the pole. The portion of the device contains upgraded parts beyond those provided in the housing of the device detailed in Example 1, including upgraded sensors, an RFID tag reader, a self-contained power supply, and a dedicated wireless radio. The self-sufficient portion of the device is installed onto the pole. The technician, using the same simple tools, such as a screwdriver and a wrench, disengages and removes a portion of the device and then replaces and engages the upgraded portion of the device, thereby completing an upgrade of the device. The technician does not need to remove the entire device to complete the upgrade, and thereby he does not need to tamper with the parts within the device that are not designed to be upgraded frequently. The process for upgrading the device similarly takes less than 10 minutes.

Example 3—RFID Start-Up Procedures

After technician upgrades a meter with the device or an upgraded portion for an already installed device, technician restarts the meter. The electronic components or the upgraded electronic components in the housing of the device scan the meter RFID tag and determine if that meter location is configured to have a sensor. If the meter is configured to have a sensor in that location, the device or the upgraded portion of the device will use either the meter's wireless radio or its own dedicated wireless radio to download a binding code from a remote management system. The binding code configures the meter, upgraded components, and sensors. The meter wirelessly connects to the new sensors. The meter display is reset, updated, and refreshed. The new meter is now ready for use.

Example 4—Environmental Pollution Sensor Network Through Parking Meters

Some devices or upgraded portions of devices already installed contain various sensors capable of collecting environmental information. Technician upgrades meters around the city with sensors capable of detecting pollution, for instance carbon monoxide and carbon dioxide. The upgraded parking meters configure themselves as described in Example 3, and the meters begin to collect pollution information. The meters transmit this data to a remote server, which upgrades the database with the pollution information. Because meters throughout the entire city are upgraded with pollution sensors, the remote server database builds a pollution map of the city.

Example 5—Waking a Meter from Power Saving Mode and Priming Payment Methods

After a preset idle time, a parking meter enters a power saving mode. A car pulls into a parking space managed by the parking meter. The sensors of the meter detect the presence of a vehicle and wake the meter from power saving mode to restore full functionality. The meter wirelessly retrieves a binding code and activates an integrated wireless payment receiver. The payment receiver is configured to accept payment through a variety of sources, for instance Apple Pay®, and is primed when the meter detects the presence of a newly-parked vehicle. The display screen is also updated upon retrieval of the binding code, allowing a user to easily pay after parking the vehicle.

Example 6—Meter Communication with City Personnel

A parking enforcement officer patrols the city hoping to hand out parking citations to meet her monthly quota. She carries a personal meter scanning device. As she approaches a parking meter, the meter's sensors detect the scanning device, and wirelessly connect to the remote management system to configure the meter to wirelessly transmit environmental information to the scanning device. The officer receives relevant environmental information in assisting her to issue parking citations, including meter identification, meter location, vehicle identification, license plate information, vehicle registration information, citation history, data indicating issuance of a citation, and data related to the type of citation issued.
